安装yum
sudo apt-get updatesudo apt install yum
Linux系统(Ubuntu)中使用国内的源地址
- 源地址列表文件路径
ubuntu系统的源列表配置文件的路径是：/etc/apt/ sources.list
为了在替换前留个备份，可以执行命令做个备份：
cp /etc/apt/sources.list /etc/apt/sources.list-bak
- 源地址列表文件的替换
不同的版本，sources.list里的url是不同的，主要是版本好不一样，例如ubuntu14.04的代号是trusty ，而ubuntu16.04是 xenial。
具体查看方法是执行命令：lsb_release -a 回车
返回的Codename就是版本代号
